Abstract

L'invention concerne des systèmes et des procédés pour le traitement non-invasif d'une région d'intérêt avec une efficacité améliorée. Les systèmes et les procédés peuvent comprendre un dispositif de traitement ayant une source d'énergie et un élément de roulement. L'élément de roulement peut comprendre une paroi disposée entre la source d'énergie et la région d'intérêt. Un traitement peut être réalisé à un premier emplacement, suivi par le déplacement du dispositif de traitement, puis une transmission d'énergie peut être terminée si un couplage entre la source d'énergie et la région d'intérêt est interrompu, ou un traitement peut être réalisé à un second emplacement si le couplage entre la source d'énergie et la région d'intérêt n'est pas interrompu.
